Dorman 594-725 Engine Harmonic Balancer

Dorman 594-725 Harmonic Balancer

This Dorman harmonic balancer is a direct replacement for select Ford and Lincoln applications, including the Ford F-150, Mustang, Expedition, Transit, Transit-150, Transit-250, Transit-350, Transit-350 HD, and Lincoln Navigator. Built with a stress-resistant rubber bond and ductile steel construction, it helps absorb engine vibration while delivering the strength needed for long-term service.

Key Features

• Direct replacement harmonic balancer for OE-style fitment
• Stress-resistant rubber bond helps absorb crankshaft vibration
• Ductile steel construction for tensile and impact strength
• 6-groove serpentine belt pulley design
• Black finish with degree markings for timing reference
• Single mounting hole design with 17.5 inside diameter and 140 outside diameter

Detailed Description

Dorman 594-725 is engineered for engines that need a reliable crankshaft vibration damper with OE-style dimensions and function. The bonded rubber element isolates vibration at the harmonic balancer, while the ductile steel body adds durability under engine load. This part number 594-725 is a practical replacement choice for drivers servicing a Ford Mustang harmonic balancer, Ford F-150 harmonic balancer, or Lincoln Navigator harmonic balancer where proper vibration control and belt alignment matter.

This part cross-references BR3Z6312B and PB1722N for the same application.

What It Helps Address

• Engine vibration transmitted through the crankshaft
• Worn or damaged harmonic balancer rubber bond
• Timing reference visibility with degree markings
• Serpentine belt drive alignment concerns
• Noise or imbalance related to a failing crankshaft damper

Installation Notes and Tips

Verify engine application by year and build date before installation, especially for 2016-2017 Ford Expedition, 2016 Ford F-150, and 2015-2016 Ford Transit models with date-specific notes. Confirm the 6-groove serpentine belt layout, mounting hole diameter, and overall dimensions match the original part before assembly. Use proper service procedures for crankshaft pulley removal and installation to avoid damage to the balancer or engine components.

Quality Assurance

Dorman manufactures this harmonic balancer as a direct replacement part with OE-style construction and materials selected for durability and vibration control. Part number 594-725 is built to meet the dimensional and functional requirements of the listed Ford and Lincoln applications.
